8 Claims; (cuss-289) w This invention relates to quills for shuttles used in looms, the nature of the invention beingsuch that a good metallic connector is utilized in a quill, and so formed as to be readily applied and wear a long time.

An object of the invention is to provide an improved quill structure whereinthe metalshortcircuiting memberis bodily inserted into the quill rather than applied thereto by spraying.

Another, object of the invention is'to provide an improved quill wherein the parts are so formed that the short-circuiting contact member may be readily slid into place and then locked by the head of the quill.

A further object is to provide in a quill an arrangementwhereby the short-circuiting contact.

embodying .the invention applied thereto, the

V quill being shown partly'filledwith yarn; Fig 2 is a view showing a quill embodying the invention partly in elevation and partly in section,

the section illustratinga certain portion of the short-.circuiting contact member;

Fig. 3 is ,an edge view of the structure shownin Fig. 2, part of the head being shown broken are w i 4 is an end view of the structure shown in Fig. 2;

Fig. 5 is a plan view in elevation of the lefthand end portion of the quill shown in Fig. 1, the same being on a slightly enlarged scale;

Fig. 6 is a sectional view through Fig. 2, approximately on the line 6-6, the same being on an enlarged scale;

Fig. 7 is an enlarged perspective view of the short-circuit contact shown in Fig. 2;

Fig. 8 is a view similar to Fig. 2, but showing a modified form of short-circuiting contact;

Fig. 9 is a perspective view on an enlarged scale of the contact shown in Fig. 8.

Referring to the accompanying drawing by numerals, I indicates a shuttle of any desired or preferred kind, and 2 a quill provided with a head 3 adapted to be received by the usual jaws 4 so that the quill may be swung into or out of the shuttle as desired.

As illustrated particularly in Figs. 2 and 3, the quill I is provided with fiat edges and flat top and bottom surfaces, with the meeting corners rounded more or less as illustrated in Fig. 6. Preferably the quill I tapers from the head 3 to the opposite end, as shown in Fig. 3, but preferably is of the same width throughout when lookcount of cheapness and lightness. The usual borev 6 is also provided and an enlargement .Iformed' at theleft-hand end as shown .in Fig.;2. A metal cap or covering 8 surrounds the enlargement 'I and with the enlargement forms the head 3. .The:

metal covering 8 is preferably providedwith-a number of punched-in portions 9 which present spurs as illustrated in Fig. 2. -In addition, part of the covering 8 is cut at spaced points and the material I8 between said points is pressed down wardly forming a notch I I. This notch is adapted to receive a pin carried by a shuttle so as to-indicate to the operator whether. the yarn I2 is .a right or left winding. Q j p The body 5 is provided. wit a notched. or grooved portion I3 having undercuts I I and I5 for receiving the flaring edges I6 and H of the contact orshort-circ'uiting plate I8. 1 This forms a dove-tail arrangement with the parts formed; to fit snugly so thatwhen the rcontact laeis slid into position from the left, as shown in Fig.1, 25

the friction will act to prevent any accidental movement.- However, the parts are preferably so. proportioned that the end I9 of the contact! is; adapted to rest against the end 20 of the grooved portion I3. A notch 2| is formed in the contact I8 and the covering 8 of the head 3 is forced into this notch so that a short section 22 of the top of contact I8 will fit snugly within the covering 8, as shown in Fig. 3. This alone will prevent any accidental movement of the contact I8.

In case for any reason it should be desirable or necessary to remove the contact I8, it will be necessary to remove the cover and then contact I8 may be slid out of its position.

It will be understood that in quills for shuttles, metal contacts are provided which coact with the stop motion of the loom and cause the same to function when the yarn I2 becomes exhausted. In the present invention this broad idea of providing some kind of metal contact is not claimed as new but the particular structure and arrangement of the contact is believed to be new in itself and in connection with the head 3 and the body 5.

As shown in Figs. 8 and 9 a contact of a modifled structure may be utilized with the body 5 and the head 3. Referring to these two figures, it will be observed that the contact I8 is a solid bar and at one end is provided with a notch 23 and at the other end with a projecting spur 24. The notch 23 functions in a similar way to the notch in n 2,o48,61

2|, while the spur 24 is adapted to be driven di- 7 rectly into the body 5 by a hammer or by being pressedtherein, or, if; desired, an aperture 25 could be formed and the extension slid therein 5 ,afterwhich the covering member 8 could heapplied as shown iniFig.'8. In this form of the I invention there is no dovetail groove but only a longitudinally extending notch of a size to fit almostexactly the contact l8.

7 desired thickness and-also thecontactjlfl, so that r they will wear for an'inde'finite length of time and, f 'infact, will usually wear aslong as the quill; ie=- us'able. r, r
